Which of the following terms describes the maximum sediment load that can be carried by a stream?

This process is called saltation. Capacity and competence. The maximum load of sediment that a stream can transport is called its capacity. Capacity is directly proportional to the discharge: the greater the amount of water flowing in the stream, the greater the amount of sediment it can carry.

What term describes the sediment carried in moving waters?

Another name for sediment transport is sediment load. The total load includes all particles moving as bedload, suspended load, and wash load ¹¹.

Which of the following rivers has the largest water discharge of any in the world?

The Amazon River discharges 7,380,765 cubic feet per second of water, and it represents 20% of the world’s riverine discharge into the ocean. The Amazon basin is now the largest water drainage basin in the world covering an area of 2,720,000 square miles.

What term describes the total sediment load transported by a stream?

what term describes the total sediment load transported by a stream? suspended load. what term generally refers to the highest percentage of the annual sediment load moved by a stream? sea level drops when water is stored in expanding ice sheets and continental glaciers.

What refers to sediments deposited from streams?

Alluvium refers to stream deposits, mainly sand and gravel. … Natural levees are constructed of machine-compacted sand and mud; artificial levees are made of concrete.

What determines the maximum sediment load of a stream quizlet?

The greater the discharge, the greater the capacity. CM- the maximum particle size a stream can transport.

In which stage River velocity is maximum or very high?

Even in straight channel segments water flows in a sinuous fashion, with the deepest part of the channel changing from near one bank to near the other. Velocity is highest in the zone overlying the deepest part of the stream.

What determines sediment load?

When particles are eroded and transported by wind, water, or ice, they become part of the transport medium’s sediment load. There are three categories of load that may be transported by an erosional agent: dissolved load, suspended load, and bedload. Sediment can be suspended in wind, water, or ice. …

What term describes erosion?

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. … Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place.

What is deposition of sediment?

What is sediment deposition? Sediment is solid material that is or has been transported from its site of origin by air, water, gravity, or ice to a field or low landscape position. Deposition occurs when the amount of sediment becomes greater than the carrying capacity of the force that is moving it.

How is sediment transported by a river?

Traction – large, heavy pebbles are rolled along the river bed. … Suspension – lighter sediment is suspended (carried) within the water, most commonly near the mouth of the river. Solution – the transport of dissolved chemicals. This varies along the river depending on the presence of soluble rocks.

Which river has the highest flow?

the Amazon

The greatest flow of any river in the world is that of the Amazon, which discharges an average of 200,000 m³/sec (7,100,000 ft³/sec) into the Atlantic Ocean, increasing to more than 340,000 m³/sec (12,000,000 ft³/sec) in full flood.

What is the term for a volume of water that is moved by a stream during a given amount of time?

Discharge is the volume of water moving down a stream or river per unit of time, commonly expressed in cubic feet per second or gallons per day.

What stream characteristic is measured by the size of the largest particle that a stream can move?

In hydrology stream competency, also known as stream competence, is a measure of the maximum size of particles a stream can transport. The particles are made up of grain sizes ranging from large to small and include boulders, rocks, pebbles, sand, silt, and clay. These particles make up the bed load of the stream.

What is the suspended load of a stream?

Suspended load is composed of fine sediment particles suspended and transported through the stream. These materials are too large to be dissolved, but too small to lie on the bed of the stream (Mangelsdorf, 1990). Stream flow keeps these suspended materials, such as clay and silt, from settling on the stream bed.

Where is sediment deposited in a stream?

Sediments are deposited throughout the length of the stream as bars or floodplain deposits. At the mouth of the stream, the sediments are usually deposited in alluvial fans or deltas, which represent a lower‐energy, more “permanent” depositional environment that is less susceptible to changes in the stream flow.

Where is sediment most likely to be deposited?

Deltas and river banks, where much sediment is deposited, are often the most fertile agricultural areas in a region.

Where does the deposition of stream load occurs?

Stream Deposition

On flatter ground, streams deposit material on the inside of meanders. A stream’s floodplain is much broader and shallower than the stream’s channel. When a stream flows onto its floodplain, its velocity slows and it deposits much of its load.

What factor determines the largest particle A stream can transport quizlet?

The ability of streams to carry a load is determined by 2 factors: Competence and Capacity. Competence of a stream measures the largest PARTICLES it can transport. A stream’s competence increases with it velocity.

How do most large rivers carry the largest part of their load?

Most large rivers carry the largest part of their load in suspension. A portion of a stream’s load of solid material consists of sediment that’s too large to be carried in suspension. … Stream transport provides a mechanism by which solid particles of various sizes are separated.

What factors increase stream load?

Flood Erosion and Deposition: As flood waters rise, the slope of the stream as it flows to its base level (e.g., the ocean or a lake) increases. Also, as stream depth increases, the hydraulic radius increases thereby making the stream more free flowing. Both of these factors lead to an increase in stream velocity.

What are the 3 stages of a river called?

Nearly all rivers have an upper, middle, and lower course.

Young River – the upper course.
Middle Aged River – the middle course.
Old River – the lower course.

What is the term defining the capacity of a river to transport the material?

Explanation: Competence defines the capacity of a river to transport the material and is represented by the largest size of a particle that can be transported at a given velocity. … It is a function of cross-sectional area of the channel and flow velocity.

Where would expect the greatest rate of channel erosion along a bend in a river?

Due to the slope of the channel, erosion is more effective on the downstream side of a meander. Therefore, in addition to growing laterally, the bends also gradually migrate down the valley. Notice the oxbow lakes and point bar formation in this meandering river!

What are the components of stream load?

The total load (quantity of sediment) of a stream can be described as consisting of three components:

the bed load – materials bounced along the stream bottom.
the suspended load – material carried in suspension in the stream water.
the dissolved load – material carried as dissolved solids in the stream water.

What is stream gradient?

Stream gradient is the grade measured by the ratio of drop in elevation of a stream per unit horizontal distance, usually expressed as meters per kilometer or feet per mile.

What happens when a stream is loaded to its capacity?

Increased capacity means the stream volume carries greater quantity of sediment. Increased competence means stream load carries greater sedimentary particle sizes. Because of increased competence, the stream may gain enough competence to carry particles as large as “pebbles, cobbles and boulders” (Gale Cengage).

Which term describes weathering?

Weathering is a term which describes the general process by which rocks are broken down at the Earth’s surface into such things as sediments, clays, soils and substances that are dissolved in water. … As weathered products are carried away, fresh rocks are exposed to further weathering.
